Google push notifications - Unauthorized WebHook callback channel

阅读更多关于 Google push notifications - Unauthorized WebHook callback channel

I'm facing problem with Google push notifications (for drive). I use service account which works perfectly for all other drive operations except drive changes watch. Below is application code which now fails with "Unauthorized WebHook callback channel" exception. I also dumped requests and responses which are generated when drive.changes.watch.execute is called. Target notification address is whitelisted in APIs & auth Push control panel (I even listed it in Javascript origins and referrers) and now I'm stuck with this 401 Unauthorized error. Does someone know where I'm making mistake? Thanks

Loading Google API Javascript Client Library into Chrome Extension

阅读更多关于 Loading Google API Javascript Client Library into Chrome Extension

问题 I've been trying to wed the google api javascript client library with a chrome extension for a while now, but it seems the chrome extension has a terrible case of cold feet. The link to the script is https://apis.google.com/js/client.js Downloading the files is messy because the script actually loads other scripts. I've tried including it in the manifest manifest.json (excerpt) "background": { "scripts": [ "background.js", "https://apis.google.com/js/client.js?onload=callbackFunction" ] },

Migrating 50TB data from local Hadoop cluster to Google Cloud Storage

阅读更多关于 Migrating 50TB data from local Hadoop cluster to Google Cloud Storage

I am trying to migrate existing data (JSON) in my Hadoop cluster to Google Cloud Storage. I have explored GSUtil and it seems that it is the recommended option to move big data sets to GCS. It seems that it can handle huge datasets. It seems though that GSUtil can only move data from Local machine to GCS or S3<->GCS, however cannot move data from local Hadoop cluster. What is a recommended way of moving data from local Hadoop cluster to GCS ? In case of GSUtil, can it directly move data from local Hadoop cluster(HDFS) to GCS or do first need to copy files on machine running GSUtil and then

Exception using HttpRequest.execute(): Invalid use of SingleClientConnManager: connection still allocated

阅读更多关于 Exception using HttpRequest.execute(): Invalid use of SingleClientConnManager: connection still allocated

I'm using google-api-client-java 1.2.1-alpha to execute a POST request, and am getting the following stacktrace when I execute() the HttpRequest. It happens immediately after I catch and ignore a 403 error from a previous POST to the same URL, and re-used the transport for the subsequent request. (It's in a loop inserting multiple entries to the same ATOM feed). Is there something I should be doing to 'clean up' after a 403? Exception in thread "main" java.lang.IllegalStateException: Invalid use of SingleClientConnManager: connection still allocated. Make sure to release the connection before

Uploading image from Android to GCS

阅读更多关于 Uploading image from Android to GCS

问题 I am trying to upload an image from Android directly to Google cloud storage. But the API does not seem to work. They have some Java samples which are tied to the App engine. I don\'t see any sample which is proven to work on Android. On Android, I tried using the json api to upload an image. I am able to upload an image object but it seems to be corrupt. Moreover generating the authentication token seems to be tricky too. I am struck with this right now. Did anyone on this earth ever tried
